It's the jing-a-ling, baby.
You're all about using music to comfort your unborn child. Unfortunately your "headphones on the belly" idea was a serious failure. And while singing could be an option, you're worried that your vocal skills are more scary than soothing. Get your baby some tunes, and get yourself a little something pretty while you're at it.

An ingenious necklace that lets you give your baby the gift of music while you get the gift of jewelry. These sterling silver charms on extra-long chains dangle daintily on your stomach to provide chiming background music for baby. Give the chain a gentle jingle to create ambiance in the womb. After a few months of pseudo-serenading, baby will be born familiar with the comforting sound of your necklace. (She'll just have to get used to your singing some other time.)
